From 225425111fee082e3be14c22c256314b85724ef8 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 28 Aug 2017 15:57:20 -0700 Subject: [PATCH] i965: Add a brw_blorp_copy_buffers() command. This exposes the new blorp_copy_buffer() functionality to i965. It should be a drop-in replacement for intel_emit_linear_blit() (other than the arguments being backwards, for consistency with BLORP).
